auter VS pure-bash-bible

For your couple of Linux servers, if you have their repositories sorted out, look at auter. Really easy to setup and schedule servers and especially when it's just a few of them.

I'm quite fond of Auter. I've been using it to automate patching of about 250 servers (RHEL, but Auter supports Ubuntu as well). It's quite flexible and easily extendable via its hooks. You can use Ansible or similar to deploy the config and cronjob to all your hosts, and then just sit back and watch it do its thing. No GUI, though.

How about auter? Auter link It's a github project built by people I work with, and it has some very nice configuration options available. We've configured environments that autoreboot for kernel updates but not everything else, options for not patching a group of systems if a different group failed for some reason (to keep from taking down all redundant systems in a patching run), unlimited automation options and scripting. In the dept I'm with now, we use a commercial product but we're really leaning into moving to Ansible. This is because it's easier to manage multiple envs with playbooks, than it would be to write all the customization into scripts for auter (and we're not allowed to completely automate the patching process in the new dept).

I believe it's been posted here before, but I also use this for reference whenever I forget the syntax to something, or know there must be a better way than what I am doing.

I'd say check out the work of William Shotts at https://linuxcommand.org/ His book, "The Linux Command Line" is free for downloading, and there are lots of references to style guides, good practices, and bash templates in the book.

There is also a shorter, HTML version at the same site: https://linuxcommand.org/lc3_learning_the_shell.php

I'm trying to get a little proficiency in all this, and just yesterday I went through the "Further Reading" sections at the end of each chapter, and captured all the likely URLs for further investigation.

One that looks really good is Dylan Araps' "Pure Bash Bible" ( See https://github.com/dylanaraps/pure-bash-bible ) Confession: I found a PDF copy at Libgen, but don't tell anyone. This and the Shotts book have also been thoroughly discussed on Hacker News in the past. (I.e., search on the two titles and you'll probably get all the opinions that you can stand, plus maybe some more hints.)

Bash is profoundly weird, but if/when you can make it work, it's slick.

I recommend taking a look at https://github.com/dylanaraps/pure-bash-bible

Additionally, Pure Bash Bible is a bit more advanced but really fun to go through it.

Here is another resource I have found useful.

Pure Bash Bible : A collection of pure bash alternatives to external processes.
